硅碳棒夹头有铝、钢和不锈钢三种材质,其中以不锈钢夹头为最好。不论那种材质的夹头,供应都比较紧张,在使用安装时,稍有不慎就会使硅碳棒折断,有的介绍以铝丝代替硅碳棒夹头的经验,经我们试用,确有好安装节约等优点。美中不足之处是铝丝熔点低,对断断续续使用的、要求温度不超过1200℃的管形炉,使用效果较好:但对长期连续处于高温或要求温度在1200～1300℃之间的工作条件,就会出现铝丝熔断,
Silicon carbide chuck with aluminum, steel and stainless steel three materials, of which the best stainless steel chuck. Regardless of the material of the chuck, the supply is relatively tight, the use of installation, the slightest mistake will make the silicon carbide rod broken, and some introduced to silicon wire instead of silicon carbide chuck experience, after our trial, indeed Good installation and other advantages. The fly in the ointment is the low melting point of aluminum wire, the intermittent use of the requirements of the tube temperature does not exceed 1200 ℃ furnace, the use of good effect: but for long-term continuous high temperature or required temperature between 1200 ~ 1300 ℃ working conditions, There will be aluminum blown,
